Application filed June 6,

To n.717. whoml t may concern.'

Be it known that I, ALEXANDER Tonus, a citizen of the United States, residing at Brooklyn. in the county of Kings and State of New York, have invented certain new and useful Improvements in Combs or Similar Articles, of which the following is a specification.

This invention relates to articles. such as combs, which are formed of a hard, brittle material, and therefore break easily in use. It is one obj ect of this invention to provide such articles with a suitable reinforcement of a durable material, such as metal, vwhich will take up the strains to which the article is subjected.

It is a further object of this invention to provide a reinforcement of the kind described which may be utilized as a frame upon which may be cast material such as vulcanite, bakelite or the like, preferably one which will take a surface polish, to form the article; and the frame is so formed that the cast material will be firmly held thereon.

Other objects and aims o-f the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part speciically referred to in the cour-se of the following description of the elements. combinations, arrangements of parts, and application of principles constituting the invention; and the scope of protection contemplated will appear' from the claims.

In the accompanying drawings,

Fig. 1 is a vertical section illustrating my invention applied to a comb.

Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1.

Fig. 3 is a perspective view of a portion of the reinforcing frame.

Fig. 4 is a view similari to Fig. 2 showing a modified form of frame.

Fig. 5 is a view similar to Fig. 2 showing a second modification.

Fig. 6 is a view similar to Fig. 2 showing a third modification.

Referring to the drawings.y I have illustrated my invention in connection with a comb, but it will be understood that the invention may be applied to a wide range of similar articles. Essentially I provide a reinforcing framle 10"having the general conguration of the finished article, in this 1922. Serial No. 566,315.

case having back yand teeth like the finished comb, but on a smaller scale. The -frame may be of a hard, durable material such as sheet iron, and the material 11 such as vulcanite or bakelite out of which the comb is to be formed is cast around said frame on all sides thereof to completely enclose it.

In order to hold the cast material firmly on the frame, the latter may be provided with openings 12 into which the cast material is run or pressed during casting to unite the material on both sides of the reinforcing frame. In addition to said openings other projecting members of the frame, in this case the teeth of the comlb, may be provided with corrugations or other surface irregularities to break the smooth surface and enable the cast material to grip the frame rmly. These irregularities may take the form of indentationsl (as shown in Fig. 8), or of saw-teeth 16 as shown in the modiiication of Fig. 4,) or of lateral openings 17 extending through the teeth (as shown in the modification of Fig. 5). The

smooth plane surface of the teeth may also be interrupted by forming the teeth of the frame as spirals 18, as shown in the'fmodiiication of Fig. 6. It may be desirable to provide addition al irregularities in the surface of the reinforcing frame in the form of shoulders 2() (see Figs. 4 and 5) extending outwardly from the front and rear surfaces, and serving to separate the material forming the back of the comb from the material forming :the teeth.

In any of the above modifications the principle is the same, i. e., the provision of irregularities in the surface of the reinforcing frame to provide gripping', members upon which the cast material may attach it, self rmly to forml a close union between vthe frame and the outer material.

The abo-ve description represents an embodiment of the principles constituting this invention, and it will be apparenlt that various changes may be made within the scope of the annexed claims.

Claims: 1. An article of the class described comprising a reinforcing frame having a back and teeth which conform to the finished article, long narrow openings and a shoulder in said bac-k and a roughened portion on said teeth and material adapted to be east upon said fiume to entirely @over the surface thereof,

2. An article of the Class described oom-Y 5 and teeth which conformi to thei'inisheci article, long nar-Tow openings in said back and the teeth oi said frame each having n"- ALEXANDER. Tonnie
